This has been bugging me for a while, finally took a look today. Under Linux on
a Thinkpad T470s I was experiencing a whitenoise/hissing sound whenever I had
headphones plugged in, and no app was actively playing sound. It happened under various kernels and distros, and it looks like it happens on other thinkpad
models as well.

Running jekyll locally can be great for testing Github pages before pushing to
your account, and it’s pretty simple. The following worked on fedora. This
assumes you already have a gh-pages repo and you are in the toplevel directory
of that repository.
